Love the MOAB and agree the 60" is the best length I have tried for the design. I had a 62" and it was not the same bow. My 60” has no hand shock, very quiet and very fast. But, you have to put a good string on them I have found. The string that comes with them makes them loud and have more vibe. A nice SBD or equal really tames them down. I have lost track of how many people have commented on how fast and quiet my bow is.
Didn't care for the Mag's I shot as much as the MOAB but never spent a lot of time with one to tune and change out strings. Can’t see where it would be any better in the end other than maybe give me a 2” shorter bow for my draw length.
I had a 66" TS III. Loved the bow, but a little too light draw and long for me to travel with and hunt the way I hunt. Was fun to shoot targets with and stump shoot. Not as fast at the MOAB from what I could tell using an equivalent arrow GPP. Traded it for a 62" TS III same weight as my MOAB. Didn't care for it as well as the 66" or the MOAB. A 64" could be the best balance for the TS III for me, but I have not found one to shoot. If I did, It would have to be a TD because I just don’t care for a one piece over 62” for travelling.
I would pick based on the length of bow you like or want.
